What the Hell is Marrella?! 

I mean, the copper blood is a pretty good pointer this is at least some sort of arthropod. Maybe an actual stem arthtropod. This would make sense: Arthropods had already diversified a lot by the Burgess shale and the had to come from somewhere, likely an extremely abundant creature given how fast arthropods formed so many distinct lineages. Other than that, I wouldn't discard proto-crustacens. Yeah, there are differences, but given how old this fossil is, this is not surprising. Even those diagnostic features had to evolve and there is bound to be forms that existed or diverged before that happened at any point between "some sort of worm" and "look, an actual crustacean!".

It's over 9000!!!!!!! Nice touch!

I always love to learn more about the bananas world of Cambrian life! Do you have any opinions on Gould’s “Wonderful Life” as a book on the Burgess Shale?

What is known about the specifics of Marrella's mouth? Does it look like any other fossil that is a contemporary? Is Anomalocaris or other relatives not appearing the same time? Could Marrella be the nymph stage of something we know in the fossil record? Or is it certain, that Marrella fossils are adult stages? Just wondering, if experts might have not clarified that yet already.

Another awesome video :)! Can’t wait for the next one.

MArilla looks like a polykete worm to me, on the horisontal instead of the verticle. switch the image so the head is facing up and the body is perpendicular to how it is now.

Opabinia is cool! Is Marella on your shirt? Love the copper blood thing, fascinating! And your mother thinks you're quite brilliant.

Just discovered it for myself today

I want that tshirt! Where did you get it!

Ooo green blood, how cool!!! What a funky little bug!

Adding a comment to boost the algorithm. Because really, only 32 comments, on a video this good??

3:46 Seeing the world through rose colored lenses. 😆

Thank you

What does the scouter say about the Royal Ontario Museum's marrella count?

_>the joke on his shirt_ Too soon, man...

so youre saying that Morella is like Crab version of that era?

Lovely video

Maybe some kinda aquatic precursor to modern Centipedes?

Cool video

I want that shirt. Where buy?

I need that t-shirt!

You have it upside down. That's a fossilized tiger nose.

Copper based blood, hmm- maybe they came from vulcan! But seriously, if they were numerous, then what they ate must have been numerous also; possibly microscopic and soft bodied so few or no fossils were created.

Maybe Marrella should be placed in its own unique group. Who said it has to belong to any of the other known Cambrian-era groups?

Awesome glasses you have there that detects fossil numbers! 😂

I guess only god knows… And he’s not talking.

Some people think the blue stains might be stomach contents of Marrella. Personally, I have no idea, but it is an interesting topic.

Is it that pinkish sauce you get on some pasta seafood dishes?

what? 9000? xD

Let us think about this for second… fossilize blood from a creature millions of years ago that lived in water just think about that for a second…🤔

It's not a very useful card, most of the other cards in the paleozoic archtype have better-wait a sec this isn't a yugioh channel

Better presentation for me . You tend to my archetype not feel I owe a both finances and emotions listening to you. Along side the facts with less barriers it is a flag for others especially female gender scientists. The listeners like I need to feel autonomy. So the mind can process . Well gare listen process retain and recall with a sense of self. This style, is better to this goal.
